1An incursion by a large number of people or things into a place or sphere of activity.

2An unwelcome intrusion into another's domain.

It should be clear to anyone but the ignorant or partisan dolts that President Donald Trump's description of the caravan as an "invasion" was not an attack by a military force.

Instead, Acosta, in "challenging" Trump's definition, adopted the one used by Democrats, progressives, liberals and everyone who opposes or detests Trump. In that, Acosta abandoned his job as a reporter and turned himself into an advocate, spokesman, apologist and poseur.

This is not to defend Trump's adolescent engagement with Acosta, the denial of Acosta's press pass or the alleged doctoring of a video recording the exchange.

The point here and in a earlier post ("CNN's Jim Acosta, Shut up and Sit down") is that Acosta has violated one of the basic ethical tenets of journalism: Objective and neutral observer. If he wanted to argue with the president, he should get himself a column, become an editorial writer or a commentator. If he wanted to become a left-wing pimp, he should stop passing himself off as a reporter and join the ACLU, Democrat Party or some such liberal group as a spokesman.

Sadly, it's a point that many of my writer colleagues have conveniently ignored, harnessed as they are to the liberal bias. Instead Acosta is heaped with praise from much of the media for "asking tough questions," ignoring the fact that he was pushing an agenda.

But Jim Acosta’s encounter Wednesday at a White House press conference was less about asking questions and more about making statements. In doing so, the CNN White House reporter gave President Donald Trump room to critique Acosta’s professionalism...

Acosta should have handed over the microphone.

Self-aggrandizing reporters like Acosta avoid the reality that their unprofessional bias inhibits their own intentions. Acosta has provided Trump supporters ever more proof of left-wing bias hence encouraging Trump to ramp up his goofy and over-the-top battle against the press. Acosta also has fueled divisiveness, which everyone says is bad for the country.

Acosta got what he apparently wanted: To come off as a martyr defending press freedom. But to me he's just another clown who tramples journalism ethics.

Your use of the Oxford and Cambridge dictionaries conveniently ignores the primary definition of invasion in each: invading a country or region with an armed force, or entering a place by force. Instead, you dwell on the secondary, metaphorical definitions.

I don't think you can argue that Donald Trump is telling his supporters that he is sending armed troops to the Mexican border to fight against a metaphor.

First of all, just because you and Donald Trump say they're unwelcome, doesn't make it so. The fact that a significant part of America, people who love their country, some of us who bled for it welcome these people render Webster's definition moot.

Also to the point of your "definition" of the word invasion, most of these people, whether it's 1,000 or 10,000 will never cross into the United States, so their invasion is into Mexico, not the U.S.

As for Jim Acosta, he is a well regarded American journalist representing the interests of the American people, who have the right to know what the hell is going on in this vastly corrupt administration.

Standing up to to Don the Con, asking questions he doesn't want to answer does not make Jim Acosta self-aggrandizing. It makes him a good journalist.

Your homework for tonight is to find definitions for "self aggrandize" and "journalism."

Wow. Gentlemen, please address the point of the column: Acosta is not an objective, neutral observer. If you can't see that, then you are as blind as the partisans who think Fox News is "fair and balanced." Enjoy your company.

I'm not arguing the other points. Yes the primary definition is an armed invasion, which the caravan obviously is not. The second definition applies. I don't know if the caravan will reach our borders. Asking tough questions is proper; in my business we used to admire "door kickers." Whatever Trump says, I have my own opinions about ILLEGAL; please don't ascribe his opinions to me.
